Today I brought home a new model 29-10. When wiping off the goo that it came slathered with, the cotton patch I was using turned a dark brown rust color as if it were removing surface flash rust. I used no oil and no chemicals. The finish appears to be more black than blue. Can anyone shed some light on what type of finish they are using now. It just doesn't look like bluing to me. Or maybe it just needs cleaned up.
